14 Claims.

This invention relates to an automatic phonograph adapted to automatically control the changing of disk records'and the playingthereof so as to operate continuously.

The principal feature of the invention resides in an automatically controlled mechanism which will play a disk record on both sides thereof before discharging it and inserting a new record, and more particularly wherein the same record is played on both sides on the usual type of turntable in connection with the usual character of tone arm and reproducer.

Another feature of the invention resides in the .means for selectively operating the machine whereby the same record may be replayed, first on one side and then the other as many times as may be desired before it is replaced by another record.

additional features of the invention. reside in the construction of the 1 mechanism for automatically controlling the raising, lowering, and positioning of the reproducer with respect to the record. Also the invention involves the mechanism for controlling the record-turning and changing mechanism in connection with the control of the reproducer and the mechanism for actuating the magazine in conjunction with the record-changing device for storing the played record and placing a new record for playing.

A further feature resides in the construction of the magazine and its actuating mechanism for permitting records to be selectively played without the necessity of their being played according to rotation. By this means the operator may select and play'any given record contained in the magazine regardless of its position therein, or on the other hand, may so position the mechanism as to cause the records to be played on both sides in rotation.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

in the drawings, Fig. 1 is a side elevation of the machine showing the mechanism in'playing position with a record removed from the magazine. Fig. 2 is a plan view looking down thereon with the mechanism in playing position. Fig. 3 is a pian view of the magazine actuating mechanism. Fig. e is a partial view of an actuating part of the magazine mechanism.

' in the drawings, there is shown the mechanism above referred to which consists of a stationary supporting table 10 on which is mounted for rotation in the usual manner, the turntable 11. Suspended from the table it there is a bracket 12 which supports a vertically extending shaft shaft 13 which is driven by the gear 16 supported on the bracket 12, said gear having a shaft connected to the beveled gear 1'7 which is driven by the beveled gear 18. Said beveled gear 18 is loosely mounted upon the drive shaft 19. Said shaft is continuously driven when the machine is in operation through the medium of a worm wheel 20 secured to the shaft 19, said worm wheel being driven by the worm 21 supported in the bracket 22 which is suspended from the table 10. The worm wheel 21 is keyed on the shaft 23 which is driven by the electric motor 24. Slidably keyed to the shaft 19 there is a clutch member 25 operated through the medium of the clutch lever 26 which is fulcrumed upon a bracket 27. One end of the clutch lever rides in the collar of the clutch while the other end is actuated through the engagement by the cam 28 which is keyed to the shaft 29. 1

f'he tone arm 30 is swivelly mounted upon the table 10 in the usual manner and carries a pivotally mounted reproducer 31 provided with r the needle 32 adapted to engage the grooves in the record 33 to be played. The base of the tone arm is provided with a plurality of rack teeth 34 meshing with the pinion 35 whichis keyed to the shaft 36 extending downwardly through the table 10. The lower end of said shaft is provided with a beveled gear 37 meshing with the beveled gear 38 which is loosely mounted on the shaft 19 and is rotatable with said shaft upon engagement thereby of the clutch 39 operated by the lever 40 which is fulcrumed upon a bracket 27 and has its other end engaging the cam 41 keyed to the shaft29. It may here be noted that the shaft 29 is clutched with the shaft 29a which is driven through the chain 42 and the gears 43 by the shaft 19. v

ihe tone arm is provided with a downwardly extending rod 44 having an eye in the lower end thereof through which the pin 45 extends, said pin having a head 46 on one end thereof and being connected with a lever 4''! at the other end, said lever being secured to the rod 48 extending downwardly toward the shaft 29 where it is connected through a shifting yoke 49 for sliding the clutch member 5Q into engagement with the clutch member 51. The member 51 is secured to the shaft 29 while the member 50 is slidably keyed to the shaft 29a.

The reproducer 31 is elevated so that the needle disengages the record by means of the link 52 5 having a pin and slot connection 52a with a lug 52b formed upon the neck of the reproducer and having its other end connected with the arm 53 which is fulcrumed at 54 to the tone arm. The free end of the arm 53 adapted to ride against a cam block 55 .secured upon the table 10. The upper end of the arm 53 is connected by a light tension spring 56 with the tone arm so that the lower end of the arm 53 will be yieldingly maintained in engagement with the surfaces of the cam block. The weight of the reproducer is suificient to overbalance the spring 56. As the tone arm moves inwardly in the playing of the record, the lower end of arm 53 engages the rear surface 55a of the block 55 and its upper end is forwardly moved against the -tension of spring 56. Because of the pin and of the cam block 55, the arm 53 is moved by the spring 56 to bring the lower end of the said arm in position to be engaged by the forwardedge'55b of theblock 55 when the tone armi starts its outward movement. During the outward movement of the tone arm, the lower end of the arm 53 rides against the surface 551) and the shape of said surface is such as to elevate the reproducer from the record by means of the link 52. When the arm 53 reaches the outer end of block 55, the tone arm is lowered onto the record by its own weight and at the same time moves the arm 53 into position to engage the surface 5512 when the inward movement of the tone arm is again begun.

In operation, it will be noted from the above description of the mechanism that when the driving motor 24 is energized the shaft 19 will be continually rotated. when the record is in place and the needle is in engagement therewith, the clutch 25 will be in engagementso that the shaft 19 will rotate the turntable and record through the gearing above described. When the needle reaches the inner groove of the record, the arm 44 carried by the tone arm willengage a suitable stop on the pin 45 so as to turn the rod 48 which throws the clutches 50 and 51 into engagement, thereby causing the shaft 29 to rotate with the shaft 19. The rotation of the shaft 29 rotates-the cams 28 and 41 which causes the clutch 25 to becomedisengaged so that the turntable will stop its rotation, and cause the clutch 39 to engage so as to rotate the vertical shaft 36 which will move the tone arm outwardly to the starting position. As the tone arm moves outwardly, the lower end of arm 53 engages the surface 55b to lift the reproducer from the record, as previously described.

In timed relation with the removal and replacement of the records on the turntable, the outward swinging movement of the arm 30 will have caused the arm 44 to engage the stop 46 on the pin 45 whereupon the clutch members producer 31 is gently lowered upon the record in playing position.

For. changing records there isprovided. a

swinging carrier pivotally mounted upon the base 60. Said carrier comprises essentially a frame 61, in which is rotatably mounted a rod 62 which carries a support 63 for supporting a record clamping head. Said head comprises a pair of clamping jaws 64 pivotally mounted on the support 63 which jaws are provided with gripping pads 65. The inner end of the jaws extend into engagement with a cone-shaped cam 66 slidably mounted on the rod 62, and are connected together by the tension spring 87 so that they are resiliently held in engagement with the cam 66. Said cam is provided with a collar 68 in which is slidably positioned the finger 69 secured to the end of the sliding pin 70. Said pin is connected by the link 71 to the bell crank lever 72 fulcrumed upon the frame 61. Said bell crank lever has a cable 73 connected to its free end and extending downwardly through the pivotal mounting of the carrier so as to engage and wind upon the drum 74. Said drum is loosely mounted upon the driving shaft 19 and is adapted to be engaged by the clutch 75 which is slidably keyed on said shaft and operated by the arm 76. Said arm is slidably mounted on the rod 77 and extends downwardly in position to be actuated by the cam 78 which is secured to the shaft 29.

The rod 62 is provided with a beveled gear 79 adapted to engage the beveled gear 80 rotatably mounted about the spindle 95 by the sleeve 80' independently of the carrier. The carrier is rotated upon its pivotal mounting through the engagement of the driving pinion 81 with the gear 82. Said pinion is secured to the vertical shaft 83 and is provided with a bevel pinion 84 on the lower end thereof. Said bevel pinion 84 is in constant engagement with the opposed beveled pinions 85 and 86 loosely mounted upon the shaft 19 and in position to be rotated thereby through the medium of the clutches 87 and 88, respectively. Said clutches are operated through the double armed clutch shifting member 89 which is slidably mounted upon the rod 77 and extends into engagement with the cam 90 which is secured to the shaft 29. Y

The under portion of the frame 61 is provided with a recess 91 into which the spring pressed pins 92 engage when the carrier has reached either of its extreme positions.

In operation, the carrier normally extends in the position shown in Fig. 1 wherein the clamping. jaws embrace the surface of the record adjacent its periphery and are spaced therefrom so as to permit the free rotation of the record. Upon the end of the record being reached and the clutch members 50 and 51 being caused to engage bythe position of the tone arm whereby the shaft 29 will be rotated, the cams 78 and 90 will be caused to turn so as to throw the clutch 75 into engagement, winding the cable 73 upon the drum so as to pull down upon the bell crank lever 72 and slide the cone-shapedcanr 66 rearwardly upon the rod 62. .This will cause the clamping jaws to engage and clamp the record 33. Substantially simultaneously therewith but following the clamping action, clutch. 87 is caused to engage for rotating the shaft 83 in the direction to swing the carrier with the jaws and the record clamped thereby counter-clockwise toward the magazine. After the carrier swings in its counter-clockwise position towards the magazine, the stationary gear80. about which the pinion 79 moves will r, ce ate cause the rotation thereof one-half revolution which will turn the jaws 180 degrees, whereby the record will be turned over and deposited in the magazine with that side which has just been played turned downwardly so that the other side will be uppermost and ready for positioning on the turntable for playing.

Thereupon, the cam '78 will operate to release the clutch '75 so that the cable 73 will unwind from the drum 74 and permit the clamping jaws to return to non-clamping position through the tension of the spring 67 which will cause the cam 66 to slide forwardly on the rod 62. Thus, the record will be released from the carrier and left in the magazine as the carrier moves away. Simultaneously with the releasing of the record the cam 90 will cause the clutch 8'7 to become disengaged and bring the clutch 88 into engagement so that the shaft 83 will be rotated in the opposite direction for swinging the carrier back toward the turntable. However, the cam 90 is so formed that the start of the return movement will be arrested immediately upon the carrier moving away from the records and the magazine sufliciently to permit the magazine to bring a new record into position to be engaged by the carrier, whereupon, the cam 90 causes the clutch 88 to be released and the clutch 8'7 engaged so that the carrier returns to the magazine in position to embrace a new record. The cam 78 is solarranged that the clutch will be engaged and the clamping jaws will clamp the new record preparatory to carrying it from the magazine to the turntable.

Through the formation of the cam 90 the clutch 8'? will then be engaged and the clutch 8'7 disengaged so that the carrier is moved clockwise. carrying the new record until it lies above the turntable, whereupon the cam '78 will cause the jaws to release the new record and it will drop into playing position.

It will be noted that the jaws of the carrier will turn 180 degrees when moving from the table to the magazine but in. returning from the magazine to the table they will not turn, or vice versa. This is for the purpose of reversing the records, and is accomplished by means of the ratchet teeth 93 which are formed upon the sleeve 80', and the pawl 94 which is mounted upon the upright spindle 95 secured in the base 60 and about which the frame of the carrier rotates.

The magazine includes a supporting framework or bracket supported upon a lowered extension of the table 10. A pair of rods 101 extend vertically upwardly from the framework 100 and form guide members between which the movable carriage 102 operates. Said carriage is provided with grooved rollers 103 which engage the rods 101for guiding the carriage and maintaining it in position while permitting the raising and lowering thereof. The frame of the carriage has a plurality of arms 104 extending laterally therefrom upon which the records 33 are adapted to rest. Said carriage is so positioned with respect to the carrier that upon the carrier swinging counter-clockwise from the turntable to the magazine, the record carried thereby is moved between arms 104 so as to be supported thereby when released. For raising and lowering, or controlling the position of the carriage in the magazine, and the records contained therein, with respect to the position of the carrier when in position to deposit a record or remove one from the magazine, the shaft 19 is extended into the magazine and is provided on the end thereof with a beveled gear. 105 adapted to mesh with the beveled gears 100 and 10'? which are loosely mounted on the shaft 108 supported in suitable bearings in the frame 100.

Said shaft 108 has slidably keyed thereon the clutch members 109 and 110 which are operated simultaneously by the shifting arm 111 so that when in one position the clutches are in neutral. The shifting arm 111 is operated by rod 112 which has connected thereto a lever 113 fulcrumed on the frame 100 with its other end engaging with the cam 114 secured to the end of the shaft 29. The extreme end of the rod 112 is provided with a roller 115 extending outwardly in position to be engaged by the dogs 116 positioned on the rod 117. The rod 117 extends vertically of the frame and is automatically rotatable therein by means of the beveled gear 118 driven by the beveled gear 119 which, in turn, is driven through the pinion 120 engaging the rack teeth 121 on the rod 122-, which rod is fixedly connected with the carriage 102. On the other hand, the rod 117 may be turned manually by the handle 123 which moves the pointer 124 over an indicating disk 125 for selectively causing the desired record to be positioned by the mechanism.

The shaft 108 is provided with 9. Geneva movement wherein the star wheel 126 is engaged by the pin 127 on the disk 128 which is secured to said shaft 108. The star wheel 126 is connected with -a pinion 129 which engages the ratchet teeth 130 on the rod 122.

Fixedly mounted upon the frame 100 there is a stationary pin 131 which is positioned in alignment witha manually movable pin 132 extending through the top of the frame 101. Said pins have pointed ends which are spaced apart just sufliciently to permit one record to pass therebetween, and are positioned in respect to the carriage so as to extend through the center holes of the records when mounted in the magazine. The upper end of the pin 131 is slightly below the plane in which the carrier operates so that the swinging thereby into the carriage will pass over the upper end thereof.

The operation of the carriage mechanism may be explained as follows. The desired records are inserted in the carriage so as to'rest upon the respective pins 104 with the vertical pin 131 extending upwardly through the holes therein. The carriage is in such position-with respect to the frame that the vacancy in the carriage for receiving the record that is being played is between the vertical pins 131 and 132. The clutches 109 and 110 are out of engagement so that the driving shaft 19 does not operate the mechanism. Upon the carrier swinging the played record back into the carriage the cam 114 on the shaft 29 is so timed or synchronized with the other cams thereon that at that instant it will operate the yielding lever 113 to move the. rod 112. The shifting arm 111 causes the clutch 11,0 to engage, whereby the shaft 108 will be rotated by the shaft 19 to elevate the carriage.

position, due to the action of the Geneva movement. This places the new record in position to be engaged by the carriage and returned to thetumtable. This operates to raise the carriage 5 after each played record has been placed thereon by the carrier until the last or lowermost record has been replaced, whereupon further upward movement of the carriage is arrested and the carriage is lowered to the bottom by the engagement of the relativelylarge dog 116 at the bottom of the rod 117. This dog, upon engaging the roller 115, will cause the clutch 109 to be engaged so that the shaft 19 will drive the shaft 108 in the opposite direction through the beveled gear 106, thereby lowering the carriage to the bottom. Upon the carriage reaching the lowermost position the hook 133 extending fromthe upper portion of the rod 11"? will engage the back side of the roller and pull the clutch shifting member 111 into neutral position so that the lowering of the carriage is arrested. Thereupon, the operation is repeated by way of raising the carriage intermittently as the records are played and replaced to bring new records into position.

If it is desired to select a record, the handle 123 may be manually operated and the pointer 124 positioned to indicate on the disk 125 such record as it is desired to play. Such manual rotation of the rod 117 will bring one of the dogs 116,-that dog corresponding to the desired record,into position to engage the roller 115, the preceding dogs being moved out of position to engage said roller by the manual turning of the rod. Therefore, the mechanism above described for elevating the carriage will be operated in the same manner to' elevate the carriageuntil that particular dog engages the roller and throws the driving mechanism into neutral position so that the carriage will be arrested in its upward movement when that particular record as represented by that particular dog is brought into position to be removed. This is permitted by means of the ratchet 134 on the rod 117 which is engaged by the pawl 135 mounted on the frame 100. Thus, this pawl and ratchet will permit the rod 117 to be automatically turned in one direction by'the rack and pinion and.121 in the automatic operation of the device but will permit the manual turning .of the rod when it is desired-to select a record.

wherein it is desired to play the same record over again the rod 136 having a button extending through the upper side of the disk is forced downwardly so that the beveled end thereof engages the pawl .and prevents it from engaging with the ratchet 134. Thus, the rack and pinion 121 and 120M111 not turn the rod 117, which remains in the manually set position with the selected dog 116 bearing against the roller 115 and rod 112 so as to maintain the clutches 109 and 110 in neutral.

In this position the fulcrum lever 113 will not operate said rod as it is made of a spring steel which will give when the cam 114 is turned in view of said rod being held back by the selected 'dog 116.

For holding the record 33 in place on the turntable so as to prevent it tipping by engagement of the, reproducer on the extreme outer edge thereof, there is provided a clamping head 140 mounted on the end of a lever 141 which is fulcrumed upon the support 142 secured to the table 10. Said lever 141 is connected by the rod 143 which is engaged by a cam 144 mounted on the shaft 29. The cam contacting end of said rod is yieldingly mounted thereon through the medium of the spring 145 so that the head 140 exerts a yieldingly clamping pressure on the record. The cam 144 is so formed that the record is released by the head 140 when the shaft 29 is rotated, and is clamped in position thereby upon completion of the rotation of the shaft 29.

From the foregoing it will be noted that the machine will play any size of record, that is, either a so-called ten or twelve-inch record, without in any way adjusting the record-changing mechanism. Furthermore, the mechanism may play the same record on both sides before changing to another record and will play the same record over again, first on one sideand then the other as many times as may be desired, by merely actuating the rod 138. It will further play any selected record of the group by the operation of the handle 123, 6r if 'desired will play them in their respective order as positioned in the magazine. It may further be stated that in filling the magazine, the pin 132 may be raised'to the top of the frame out of the way so that all the records may be quickly inserted, whereupon said pin is placed in position extending through the center holes thereof.
